Riding 2 up extended

I am thinking of extending my swingarm 3-4 inches.I will be lowering the rear 2" to return to stock height. My wife rides with me a few times a month.Will this be a problem? I know if I extend it out more than 6" the rear tire will hit the under tail but what about at 3-4". I just want to move the rear tire back a few inches for the look, I will stay with the 190 rear tire. Any help will be great.

You can go down 1" if you ride carefully, down 2" and your tire will put some unwanted stripes or worse case some new air vents in your undertail. A Tiger Tail would be your best bet if you want to go 2''.

Tell him your bike setup, overall anticipated riding weight range, and he'll recommend a spring for you. You can also try the thread titled "Rear Spring/Shock Upgrade" in General Bike Related forum just posted last night...by me. Might be some interesting info there for you....
